The strongest castle in Heroes of Might and Magic IV.

But the spell "General Theft" removes all blessings and life and nature and death, such as vampirism and chaos, so Haven is stronger and deserves at least 2nd place, and even 1st place because against Sylvan, it has banishment and banishment again.

Again, the amulet protects against 50% damage and magic defense +50%. That is, the army has a small immunity. + there are also artifacts like cloaks that give protection from spells. If you try to sum everything up, then 50% protection from the amulet + 50% from artifacts:)
